Upgrade YUI Compressor

Issue

CQ uses YUI Compressor to control the handling of client libraries for JavaScript and CSS minification to preserve the operational qualities of the code while reducing its overall byte footprint. The cq5.5 uses yuicompressor-2.3.6.jar. The latest yuicompressor-2.4.7.jar includes fixes for several bugs, such as media queries handling.

Solution

Find the bundle that has yuicompressor. In CQ5.5, the bundle is Adobe Granite UI Commons (com.day.cq.cq-widgets) http://<host>:<port>/system/console/bundles/com.day.cq.cq-widgets
